ABSTRACT
Introduction
Metastatic urothelial carcinoma is an aggressive malignancy with a poor prognosis. Research in recent years has led to the approval of new treatments that offer improved survival for patients. Enfortumab vedotin-ejfv is a first-in-class monoclonal antibody drug conjugate that binds Nectin-4, a protein expressed on bladder cancer cells, and delivers the tubulin toxin, monomethyl auristatin E, into the cell causing cell death. Enfortumab vedotin-ejfv has changed the standard of care treatment in urothelial carcinoma with a high response and disease-control rate, acceptable toxicity profile and improved overall survival for patients who previously had limited options after failure of chemotherapy and/or immunotherapy.
Areas covered
We review the pharmacology, clinical efficacy, safety, and tolerability of enfortumab vedotin.
Expert opinion
Enfortumab vedotin-ejfv has shown promising efficacy and safety in pretreated patients with advanced urothelial carcinoma. It is currently being evaluated in clinical trials in earlier lines of treatment and in combination therapy.
Article highlights
Urothelial carcinoma is a common malignancy that has a poor prognosis in advanced disease
Enfortumab vedotin is a novel antibody drug conjugate that binds Nectin-4, a protein highly expressed on urothelial carcinoma cells and delivers monomethyl auristatin E, a tubulin toxin, directly to cells
Enfortumab vedotin has been studied in phase I-III clinical trials and has improved outcomes coupled with acceptable tolerability for pretreated patients with advanced urothelial carcinoma
Early results in the investigation of combination enfortumab vedotin and pembrolizumab therapy have shown promising efficacy and durability.
Enfortumab vedotin is currently being investigated as a treatment earlier in the disease course and in combination therapy
